Excellent Control Valve Actuator White Paper from Rotork

Here is a white paper from electric actuator manufacturer Rotork pointing out the benefits of electric actuators over pneumatic.

Electric control valve actuators provide excellent performance and are ideal for oil and gas wells in remote production fields. Instrument air supply systems are costly and require significant energy to run. If mains power isn’t available, an instrument air supply isn’t practical, especially when only a few control valves are in use at a location. Solar powered DC electric actuators are ideal for such an application.
